无法在任何地方找到解决方案，我真的希望这是可能的。
我正在编写一个 Jira 小工具，我有一个包含 2 个字段的配置屏幕。一个是快速查找项目选择器；您键入它会找到项目，然后单击您想要的项目。
第二个字段是组件。您可以选择要作为过滤依据的项目组件。但是，每个项目的组件都不同，因此组件字段填充了在“配置”部分的“args”部分的小工具中指定的 AJAX 调用。
唯一的问题是此 AJAX 仅在首次加载小工具时被调用；即:在选择项目之前，结果始终是“选择项目”。
我需要一种方法来在所选项目发生更改时重新运行此 AJAX 调用。
这可能吗？或者有替代解决方案吗？我试过定时器来检查变化，但也有一些问题；主要是我无法访问/更改组件下拉框字段。小工具只会拒绝加载。
更新:下面是小工具的 Javascript。如您所见，我添加了一个 refreshComponents() Javascript 方法，它可以在给定项目 ID 的情况下检索组件，但是我无法将其附加到适当的事件。此外，我似乎无法使用 jQuery 或普通 JS 之类的方式直接更改页面上的任何组件

最佳答案
我想你需要把你的组件字段变成一个 Callback Builder .
在回调函数中你需要做一些事情:
- 通过 AJAX 请求检索选项
- 呈现下拉列表
- 附加事件处理程序以在特定事件发生时刷新列表
您的新组件字段可能看起来像这样......为了简洁起见，我假设您已经使用了 jQuery。
{
userpref: "component",
label: "Component",
id: "component_field_id"
description: "Choose which issue type you would like",
type: "callbackBuilder",
callback: function(parentDiv){
function renderOptions(options){
// Remove elements from the parentDiv and replace them
// with new elements based on the options param
// You can use gadget.getPref('component') to ensure you
// mark the right option as selected
}
function getOptions(){
$.ajax({
url: "__ATLASSIAN_BASE_URL__/rest/severity-gadget/1.0/severity-issues/getComponents.json",
data: {
// You might be able to get hold of the selected value
// from the gadget object instead of like this
projectId: $("#filter_projectOrFilterId_id").val()
}
}).done(renderOptions);
}
// Retrieve and render options on gadget load
getOptions();
// Retrieve and render options on an event
$(parentDiv).on("update-options", getOptions);
}
}
此外，您需要在项目选择字段值更改时触发一个事件。在您的 JS 代码的其他地方(不在小工具定义内)您需要放置这样的代码，但您需要确认项目/过滤器选择器的 CSS 选择器:
$(document).on("change", "#filter_projectOrFilterId_id", function(){
$("#component_field_id").trigger("update-options");
});
我没有对此进行测试，但这就是我尝试实现您所要求的方式。
